Overall, I really like the B&P shells. I use their 20s, 16s and 12s including their "Dispersantes" (spreaders)
Curiously, some of their loads are incredibly dirty - the inside of my barrels look as though they've gotten feathers after a few rounds. But they clean right up and I clean my guns after every use anyway.
I like the fact that they publish pressures - not sure why but I think it says something good about a company that offers such info.
Unfortunately I got overenthused about one of their offers and now have a huge stack of flats. Drat! Means I gotta shoot more.
